Wiring diagram for grant ignition coil 8 valves

Coil purpose

The main job of the ignition coil on a Grant vehicle is to generate a reliable and powerful spark at the plug that effectively ignites the fuel mixture in the combustion chamber. A huge voltage is generated in the coil, which can reach 40 kV, which is a lot, for example, in a regular household outlet there is only 220V.

The ignition coil is also called the ignition module; both names for this part will be correct.

How to replace spark plugs in Lada Kalina

Replacing spark plugs is an important procedure that is performed every 30 thousand km or in case of their malfunction. The reason why spark plugs are replaced unscheduled may be unstable engine operation, excessive fuel consumption or poor engine starting. In addition, poor throttle response or when the engine stalls can be evidence of faulty spark plugs. You can even determine the condition of the spark plugs by external signs; below I will give a table by which you can decide whether you need to replace the spark plugs or not.

Today I will talk about how to replace spark plugs on a VAZ 2170, 2171, 2172 (Lada Priora 16 valve)

Before you start replacing, take care of new spark plugs, choose one you like from the options in the auto store.

Replacing spark plugs on a Lada Priora is impossible without a special 16″ socket wrench with an extension. There must be a magnet in the spark plug wrench or head so that the spark plugs can be held suspended.

HOW TO REPLACE CANDLES FOR VAZ 2170, 2171, 2172 LADA PRIORA WITH YOUR OWN HANDS.

If you have everything, then you can proceed:

1. First, remove the decorative plastic casing.

2. Next, disconnect the ignition coil terminal.

3. Unscrew the coil mounting bolt.

4. Using a flathead screwdriver, remove the ignition coil.

5. The spark plug is located in a recess, in the so-called spark plug well, so to unscrew it you will need an extension cord.

6. Be careful, if you notice traces of oil in the spark plug well, be sure to find out its origin; the engine may need immediate replacement of the cylinder head gasket.

7. If this is your first time replacing spark plugs, then it will take some effort to unscrew the spark plugs; in some cases it is simply impossible to do this with a simple spark plug wrench. To do this, you will have to buy a special spark plug socket with a knob.

8. So, unscrew the spark plug, be careful not to accidentally break the spark plug insulator, since it will be quite difficult to remove the fragments, and if, God forbid, they get into the cylinder, then you will need to completely disassemble the cylinder head.

9. Remove the spark plug from the well; if this does not work, use the removed ignition coil, put it on the spark plug shank and try again.

10. The candle has been removed, now you can look at its condition.

11. Draw a conclusion based on the table above. If the spark plug insulator is clean and does not fall into any of the categories, everything is fine with your engine.

12. Install the new spark plug into the head, then reinstall.

13

Attention! Tighten the spark plug without using a wrench; the spark plug should twist easily without any effort. If you break the threads in the cylinder head, you will need repairs, which are not cheap, plus you will create a lot of trouble for yourself

14. Do everything carefully and take your time. When the candle is screwed in, use the wrench and tighten the spark plugs. Again, remember that everything should be in moderation; if you overdo it, you can break the thread.

15. Now all that remains is to put the ignition coil in place, tighten the mounting bolt and put the connector in place.

Repeat the procedure for all other spark plugs.

That's all, now you know that replacing spark plugs on a Lada Priora is a procedure that you can do yourself!

Wiring diagram

Many people wonder how to connect high-voltage wires; most often this question arises after replacing spark plugs. It is necessary to connect the wires in strict sequence, but if they are mixed up, the car may not operate correctly or may not start at all.

To connect the wires correctly, you need to know the cylinder counting order. On the Grant, the cylinders are counted from the timing belt from left to right, that is, the leftmost cylinder will be number one, and the rightmost cylinder will be number 4.

There are 4 pins on the coil, which are marked with numbers. Each number indicates a cylinder number. The wire of the first terminal should be connected to the spark plug of the first cylinder, etc.

Ignition switch and features of its replacement

The ZZ is secured with one screw and is located on the steering column on the right under the steering wheel. Its design includes a locking device and a contact group. They are interconnected, working synchronously, and are activated using the ignition key.

When diagnosing faults in the electrical circuit, it is necessary to check whether the contacts close correctly when the position of the key changes. If any irregularities in the operation of the ignition protection are detected, it should be replaced (the author of the video is Renault Repair).

The procedure for replacing the ZZ on the Lada Largus consists of the following steps:

1. Before work, disconnect the negative terminal from the battery to turn off the power supply to the car.
2. Next, remove the steering column casing.
3. At the next stage, by releasing the latch, we disconnect the connector with the wires of the contact group.
4. Then, inserting the key into the ignition switch and setting it to the first position, remove the 33 wires from the dashboard.
5. Next, unscrew the bolt that secures the ZZ.
6. Use a screwdriver to press out the latches and remove the 3Z from the housing.
7. We dismantle the faulty unit.
8. Having installed a new spare part, we assemble it in the reverse order.

Symptoms of a problem

It happens quite often that the ignition coil fails for one reason or another. Most often, coil failure is caused by moisture, and due to the low location of the part itself, moisture quite often gets on it.

Malfunctions:

• Two cylinders (1-4; 2-3) do not work at once;
• The car jerks and accelerates poorly;
• Difficulty starting the internal combustion engine;

If your car has such malfunctions, then most likely the ignition coil is faulty.

Self-diagnosis of the module

You can check the module in the following ways:

1. Checking for weight. To carry out the test you will need a multimeter. The tester should be set to resistance measurement mode. One probe of the tester must be connected to pin 15, and the second one must be shorted to the housing. If the unit is working properly, the resistance should tend to infinity.
2. Checking the primary windings of the short circuit. The primary windings are checked for breaks using a tester. To check, you need to connect the probes of the meter to the outer contacts on the short circuit. If the resistance tends to infinity, this indicates the presence of a break in one of the windings.
3. Checking secondary windings. Since there are two windings, the test is carried out in two stages. First you need to check the short-circuit winding of cylinders 1 and 4. To do this, the multimeter probes must be placed in the appropriate terminals. A resistance of about 5.4 kOhm is considered normal. If the resistance tends to infinity, then there is a break in the winding. The short-circuit winding of cylinders 2 and 3 is checked in the same way.

In case of malfunction, the ignition module is replaced with a new one.

Examination

The ignition coil can be checked in two ways: using a diagnostic tool and using a multimeter.

The diagnostic device provides 100% information about the condition of the part, but this method is not always affordable for many Grant owners. Therefore, many people check the coil using a conventional multimeter.

Lada Granta black little devil › Logbook › The ignition coil 8 kl (ignition module) was faulty

Hello everyone. In general, this started a long time ago, about 2 months ago. The engine seemed to be working normally with the sound of nothing unusual, but the exhaust sometimes jumped from the silencer as if the car had sneezed a little. I didn't even attach any importance to it. But about 2 weeks ago, at an intersection, when she started moving, the check light came on. I parked, pressed the error function on the BC state and I got these 4 errors. (1) 0351-Ignition coil, open circuit check, primary circuit current is less than the threshold value. (2) 0363-Random or multiple misfires detected for protection converter.(3) 1301-Misfires were detected to protect the converter in the 1st cylinder.(4) 1304-Misfires were detected to protect the converter in the 4th cylinder. I cleared the errors, the check went out, the car started up normally, the engine did not fail, I drove off then I forgot. Three days later the same thing happened again, but the check no longer lit up on the BC state there was error 0351. I reset it again and the car drove fine. Throughout the whole day there was this crap engine Troil and for some reason it only happened at that moment when I had to get going. The next day I went to our wonderful spare parts store CAR-CITY and decided to buy a new ignition coil, we have a salesman called Joseph who has it in our Lada city they probably know him. He tells me before buying a new one, check yours. I brought him my coil, he checked it on some kind of device that imitates candles. There was a spark on all contacts. He said that my coil was intact. says the problem lies elsewhere. I took the wires and spark plugs from him and installed them. At first it didn’t bother me, but then it all started again. I went to the nearest service station to see an electrician. The electrician looked and said I need to open the computer and resolder some 2 microcircuits. I thought, now I’ve come and I need to open the computer (I didn’t want to do that). By the way, he also checked my coil with the same crap. He said the price, like 3 pieces of diagnostics to identify the cause, and then work of 6 pieces. I left to look for another service station, then I called an electrician, he reflashed my computer, his name is Oleg, he works on March 8, Kalinin is also familiar to many who have a Lada. So he tells me that since the errors appear on cylinders 1 and 4, feel free to change the coil so that the instruments don’t show it there. It’s like, if 2-3 cylinders, then it’s the microcircuits in the computer that have burned out, or the fuel pump doesn’t have enough power and there’s a misfire signal. In short, I changed the ignition coil and everything disappeared and the exhaust became a uniform sound without any skipping sneezing. I think this is the sneezing and This is the first sign that something is wrong with the ignition. The mileage at that time was 61 thousand and a penny. At the same time I changed the front brake pads and took the same Korean HI-Qs as before, I drove more than 32 thousand km on them, I think they would have covered 3-4 thousand more. They wear in during the first kilometers and do not creak, I liked them and recommend them. Just yesterday, Tsuka hit the mother of a dog. She ran out before she could dodge and hit her with the right edge of the bumper. The dog has medium withers, about a generation high. The bumper cracked and a piece broke off from the lip. Damn it was so unpleasant. The living dog lay down, whined, got up and ran away. It’s good that when I was dodging it, there was no one who was driving nearby. When it hit, it crap on my front door)). It’s not nice how the year started.

At the top are my old spark plugs, they're like new ones.
